Why are some rooms warmer than others?

This is usually just a matter of balancing. Meaning adjusting the airflow to each room so they all even out. Or sometimes making the rooms you choose more comfortable, and unused rooms less so. If a room is heating or cooling much faster than other rooms, the airflow can be reduced to that room to even things out and then send more air to other areas.
